  1. Hi mike
    I am unable to decide which bourns rotary encode to use as rs and farnells do not seem to mention detents?
    Would it be possible to give me the rs or farnel part number of the right encoder.
    All the ones I found say the step sequence. At24

    1. Hi Barrie,

      Just had a look and the Farnell site I visited at Farnell has a huge range and they clearly say whether they have detents or not. I’ve shown a link below so you can select to your budget.
